v0.5.0

Pure worktree-aware dev launcher: collision-free ports, processes, and per-worktree databases.

Removed

• The agent-fleet dispatcher (ataegina run / ataegina status) and its config keys. ataegina is now solely the worktree dev launcher; orchestration is left to whatever tool you already use.

Fixed

• ataegina init no longer aborts under set -e during stack detection (two cases: a package.json with no dev script, and emit_config ending on a falsy test). Covered by tests/init.bats.

Changed

• A bare ataegina now prints usage instead of silently running up.

Added

• bats-core test suite and GitHub Actions CI (shellcheck + bats on macOS bash 3.2 and Linux + release-verify).
• Release-hygiene docs: CHANGELOG, SECURITY, CODE_OF_CONDUCT, issue/PR templates.

See CHANGELOG.md for full details.
